From the WABI-TV5 & CW Forecast center:
The ridge of high pressure that has produced the bright and chilly conditions across New England the past two days will continue to control the weather here tonight and tomorrow. With the high sitting on top of our region tonight the skies will be clear and the wind will be light, which will allow for radiational cooling. Low temps across Maine tonight will range from the mid teens to mid 20s, with the coolest readings being found across the valleys up north. Under partly to mostly sunny skies tomorrow the temps will remain a bit below normal as highs range from the upper 30s north to mid 40s south.
On Wednesday clouds will slowly begin to move into New England from the west as the ridge of high pressure that has produced the sunny conditions slips off to our east. A light southerly breeze on the backside of the high will allow temps to continue to warm across the Pine Tree State. On Thursday a storm moving northeast from the Great Lakes Region up into Ontario will bring an increasingly mild southerly airflow to Maine and the rest of New England. Showers will break out from west to east across Maine as the storm moving into Canada Thursday pulls a cold front into our region later in the day and evening. A gusty northwest breeze on the backside of the cold front will help usher a chilly airmass back into our region for both Friday and Saturday.
Tonight: Mostly clear, light wind and chilly, with low temps in the mid teens to mid 20s.
